In 1.5.x, the following code in controlDict samples and writes to frontProbes/0/p and backProbes/0/p during run time
frontProbes
{<blockquote>type probes;
functionObjectLibs ( "libsampling.so" );
probeLocations ( ( -1 0 1) (-1 0 2) );
fields ( p );
}
backProbes
{
type probes;
functionObjectLibs ( "libsampling.so" );
probeLocations ( ( 1 0 1) (1 0 2) );
fields ( p );
}
</blockquote>

However, using dictionary files as the following code does will cause both sets of results to be written to probes/0/p resulting in an unusable output file.
frontProbes
{<blockquote> type probes;
functionObjectLibs ( "libsampling.so" );
dictionary frontProbesDict;
}
backProbes
{
type probes;
functionObjectLibs ( "libsampling.so" );
dictionary backProbesDict;
}
</blockquote>

The issue is caused by different OutputFilter initialization in Foam:: OutputFilterFunctionObject<outputfilter>::start()

OutputFilterFunctionObject.C
IOOutputFilter.C
IOOutputFilter.H
The modifications attached solves the problem by providing an additional constructor in IOOutputFilter. The new constructor allows OutputFilter to be constructed with specified name. I am new to OpenFOAM development. Could someone review the code changes to make sure it fits the OpenFOAM standards?

Thanks.

The changes you proposed are fine and the new constructor IOOutputFilter can replace the existing one with only minor change. I have applied these changes to 1.5.x.

Thanks

You forgot to check in the bug fix in probeLocations.C, line 47.
